Abstract
A hand-held power tool for at least percussively driving a working tool (2) along a percussion axis (A) and including a chuck (4) for receiving the working tool (2) and including a receiving sleeve (6, 6′) fixedly connected with the chuck (4) for joint rotation therewith and for limited axial displacement relative thereto, at least one locking member (7) radially displaceably supported in the receiving sleeve (6, 6′) for axially securing therein a shank (3, 3′) of the working tool (2) insertable in to the receiving sleeve (6, 6′), and an axially extending anvil (8) securable in the receiving sleeve (6, 6′) for closing a power tool side end of the receiving sleeve (6, 6′).
Claims9
A chuck for a hand-held power tool and designed for receiving a working tool (2) comprising a receiving sleeve (6, 6′) fixedly connected with the chuck (4) for joint rotation therewith and for limited axial displacement relative thereto and open at least at one of opposite ends thereof;
- at least one locking member (7) radially displaceably supported in the receiving sleeve (6, 6′) for axially securing therein a shank (3, 3′) of the working tool (2) insertable in to the receiving sleeve (6, 6′), and an axially extending anvil (8) fixedly elastically securable in the receiving sleeve (6, 6′) by an elastic intermediate layer for closing a power tool side end of the receiving sleeve (6, 6′).
A hand-held power tool for at least percussively driving a working tool (2) along a percussion axis (A), comprising a chuck (4) for receiving the working tool (2) and including a receiving sleeve (6, 6′) fixedly connected with the chuck (4) for joint rotation therewith and for limited axial displacement relative thereto and open at least at one of opposite ends thereof;
- at least one locking member (7) radially displaceably supported in the receiving sleeve (6, 6′) for axially securing therein a shank (3, 3′) of the working tool (2) insertable in to the receiving sleeve (6, 6′), and an axially extending anvil (8) fixedly securable in the receiving sleeve (6, 6′) for closing a power tool side end of the receiving sleeve (6, 6′), wherein the anvil (8) is fixedly elastically secured in the receiving sleeve (6′) by an elastic intermediate layer (22).
